Referring to the drawing in detail, reference character I designates a pen holder which is recessed at 2 to receive the sleeve member 3. The sleeve member 3 has an exterior surface formed by cylindrical portion 4 and a tapered portion 5. The end of the sleeve 3 is chamfered as at 6 to coact with a simiiarly chamfered portion 2a of the recess-on socket 2. The sleeve 3 is apertured at i at one side thereof to allow a small deposit of glue or cement to be employed for securing the sleeve 3 in position in socket 2. The interior wall of sleeve 3 is cylindrical and provides a recess into which the pyralin plug 8 is inserted. The pyralin plug is shaped, as shown more particularly in Figs. 8 and 9,120 include the substantially cylindrical portion 9 and a nib supporting portion ID. The pyralin plug 8 is provided with a pair of longitudinally extending slots which extend in planes normal to each other. One of these slots is shown at H and forms the ink retaining means for the pen. The other slot is shownat 2 and extends beyond the limits of slot 1 I the nib supporting portion of the plug and terminates short of the extremity of the plug which is inserted in the socket 2, as illustrated more particularly in Fig. 2. There are ink feed channels on opposite sides of plug 8 which connect the slots H and 2 around the exterior surfaces of the plug 8, as shown at. Thenib supporting portion 10 is also provided with recesses l5 which serve to facilitate the feeding of ink to the pen point. It will be observed that slot 12 extends to within a relatively thin wall thickness I 6 of the nib supporting portion it of the plug 8. The shape of the plug 8 is such thatpen point I! may be inserted into the narrow arcuate shaped space 18 which is left in between a sernicylindrical portion of plug 8 and the interior cylindrical surface of sleeve 3. This space is provided because of the compression to which the two halves of the plug are subjected. The two halvesof the plug perform a dual function, that is, they serve as a grip for the spring shaped space 18 insertion between the exterior surface of the plug and the interior surface of "sleeves and is secured more firmly in position by means of the resilient engagement of the spring I member 20 therewith.

Thespri'ng member 20 is shown more clearly in Fig. 10. The member comprises a wire bent 7 upon itself having arms 20a and 20b. Arm 2% 55 is extended 'throughthe-slot H. Arm 20a extends through slot l2. 7 Arm 29a is bent to include a portion 28c which conforms with the recess l5 in'plug 8. The wire member 20 has a bowed portion which contacts with the undersurface of the pen point I! and particularly at the position Ha of the pen point where the slit in the pen point terminates. The portion 20a of the resilient member 20 which bears against the undersurface of the pen'point 1'! tends to force the point into closer frictional engagement with the interior cylindrical surface of sleeve 3.

Spring member 20 serves as a capillary feed for ink retained in slots H and I2 for delivering ink continuously to the pen point. The resilient member 26 so coacts with the channels l4 and the recesses I5 in plug 8 that a continuous feeding of ink 'is'eil'ected from slots I! and (2 to the pen point. The size of slots II and I2 is such that each dipping operation.

I have found the pen of my invention highly practical in its manufacture, production, and operation and, while I have described my invention in one of its preferred embodiments, I desire that it be understood that modifications may be made and that no limitations upon my invention are intended other than are imposed by the scope of the appended claims.

What I claim as new and desire to secure by Letters Patent of the United States is as follows:

said wire member establishing a feed path for ink from said slots to said pen point.

,6. A pen comprising a pen holder having a socket in one end thereof, a sleeve member mounted in said socket, a plug, said plug having a longitudinally extending slot therein for rendering diametrically opposite portions of said plug displaceable inwardly for facilitating the insertion of said plug in said sleeve, a pen point mounted with respect to said plug and secured between a cylindrical portion of said plug and the interior wall of said sleeve, a second slot extending longitudinally of said plug at an angle to the aforesaid slot, and a wire member bent upon itself and extending through each of said slots, said wire member engaging said pen point and establishing a capillary feed path for ink from said slots to said pen point.

7. A pen comprising a pen holder having a socket in one end thereof, a sleeve member mounted in said socket, a plug, said plug having a longitudinally extending slot therein for rendering diametrically opposite portions of said plug displaceable inwardly for facilitating the insertion of said plug in said sleeve, a pen point mounted with respect to said plug and secured between a cylindrical portion of said plug and the interior. wall of said sleeve, a second slot ex tending longitudinally of said plug at an angle to the aforesaid slot, and a wire member bent upon itself having one arm longer than theother, the longer arm extending between the displaceable portions of said plug and rigidly gripped thereby and the shorter arm yieldably engaging said pen point and providing a capillary feed path forink from said slots to said pen pint.,
